What are the 2 factors that multiply 15000 and adds up to 5

s2008m [1.1K]

Ok so there are no real solutions for xy=15000 and x+y=5
there are immaginary solutions though so

xy=15000
x+y=5

x+y=5
y=5-x

x(5-x)=15000
-x^2+5x=15000
0=x^2-5x+15000
quadriacic formula
if ax^2+bx+c=0, then
x= $\frac{-b+/- \sqrt{b^{2}-4ac} }{2a}$

x^2-5x+15000
a=1
b=-5
c=15000
x= $\frac{-(-5)+/- \sqrt{(5)^{2}-4(1)(15000)} }{2(1)}$
x= $\frac{5+/- \sqrt{25-60000} }{2}$
x= $\frac{5+/- \sqrt{-59975} }{2}$
x= $\frac{5+/- 5i\sqrt{2399} }{2}$
so the numbers are
$\frac{5+ 5i\sqrt{2399} }{2}$ and $\frac{5- 5i\sqrt{2399} }{2}$
